Lithium Heparin Blood Collection Tubes: Specifications, Ordering and Support FAQ

Below you will find direct answers to the questions buyers, distributors and lab procurement teams most often ask about lithium heparin blood collection tubes from Shijiazhuang BDT Heating Pad Co.,Ltd. Each answer is drawn from the company's confirmed product documentation. Where a specification has not been publicly confirmed, that is noted rather than assumed.

What is a lithium heparin blood collection tube and what is it used for?

A lithium heparin blood collection tube is an anticoagulant tube that uses lithium heparin as its additive. Lithium heparin inhibits clotting by binding thrombin and other clotting factors, allowing plasma to be separated from whole blood for downstream analysis. It is widely used in clinical chemistry and other plasma-based assays. Shijiazhuang BDT Heating Pad Co.,Ltd. offers both venous (vacuum) and capillary formats of this tube type.

What is the difference between a capillary lithium heparin tube and a standard venous lithium heparin tube?

The Heparin Lithium Capillary Blood Collection Tube is designed for capillary blood sampling — typically collected by fingerstick or heelstick — making it suitable for paediatric patients or situations where venipuncture is not practical. The Lithium Heparin Tube (venous format) is intended for conventional vacuum-assisted venous draw. Both are available from Shijiazhuang BDT Heating Pad Co.,Ltd., and both use lithium heparin as the anticoagulant to support plasma separation and reliable anticoagulation.

Does Shijiazhuang BDT Heating Pad Co.,Ltd. offer a lithium heparin tube with a gel separator?

Yes. The Gel Separator–Lithium Heparin Tube combines lithium heparin anticoagulation with an inert gel barrier. After centrifugation the gel migrates to form a stable separator layer between the plasma and cell fraction, which helps preserve sample integrity during transport and storage. This product is listed under the company's blood collection tube range for whole-blood and plasma diagnostic applications.

What is the Sodium Fluoride–Lithium Heparin combination tube used for?

Shijiazhuang BDT Heating Pad Co.,Ltd. also lists a Sodium Fluoride–Lithium Heparin Tube. The sodium fluoride component acts as a glycolytic inhibitor, helping to stabilise glucose levels in the specimen, while lithium heparin provides anticoagulation and supports plasma separation. This dual-additive format is appropriate for tests where glucose preservation alongside anticoagulation is required.

Are the tubes also suitable as heparinized capillary tubes for blood gas or other capillary tests?

The capillary blood collection tube range from Shijiazhuang BDT Heating Pad Co.,Ltd. includes heparinized capillary tubes designed for capillary collection procedures. The product documentation references capillary blood gas collection applications and describes the tubes as suitable for precise capillary blood sampling and testing. Specific suitability for a given assay should be confirmed with the company directly before ordering.

How do I enquire about wholesale pricing, minimum order quantities, or exclusive agency arrangements?

What should I confirm before placing a first order?

Before finalising an order for lithium heparin blood collection tubes, buyers are advised to:

• Specify the format needed — capillary or venous; with or without gel separator; plain lithium heparin or sodium fluoride–lithium heparin combination.
• Request current certifications and regulatory documentation applicable to your target market (e.g. US, EU, Middle East or Southeast Asia), since the company's site references ISO certification for its blood collection tubes but specific certificate numbers and scopes require direct confirmation.
• Clarify labelling and packaging requirements for import compliance in your country.
• Request samples if your procurement process includes a product evaluation stage.

All technical specifications, certifications and export compliance details must be verified directly with Shijiazhuang BDT Heating Pad Co.,Ltd. before purchase.
